The male imago is characterized by the rugulose median dorsal surface of the gonocoxite. In other details it closely resembles P. culiciformis. The presumed female has about 3 setae on anepisternum, about 4–5 sensilla chaetica on each ta 1 of p 2 and p 3, and about 40 setae on segment X. The presumed pupal exuviae has dark brownish tergites; plastron plate about 1.3 times as wide as apical constriction of horn chamber; thoracic horn about 0.53 mm long; and anal lobe with about 40 spines on outer margin, none on inner margin, and apical spines enlarged, but not set off from remaining spines. Etymology. From Latin, rugulosus, full of wrinkles, referring to the rugulose median dorsal surface of the gonocoxite Male imago (n = 5, except when otherwise stated) Total length 3.21–3.82, 3.44 mm.
